About

Enlarged project area map The culvert at Butte Creek on U.S. 101 is in critical condition. We're replacing the existing culvert with a bridge.

This will create an easier passage for native migratory fish, like salmon. Improving fish passage aligns with our commitments to the Oregon Plan for Salmon and Watersheds.

We will:

Remove the old culvert.
Build a new bridge.
Replace the existing guardrail.

By replacing the failing culvert, we'll make the road safer and more stable which will reduce maintenance costs.
